. Compounds of formula I are modulators for amyloid beta and thus, they may be useful for the treatment or prevention of a disease associated with the deposition of β-amyloid in the brain, in particular Alzheimer's disease, and other diseases such as cerebral amyloid angiopathy, hereditary cerebral hemorrhage with amyloidosis, Dutch-type (HCHWA-D), multi-infarct dementia, dementia pugilistica and Down syndrome.

Four small, targeted libraries of differentially substituted amino pyrimidines were synthesized in moderate to good yields. Excellent regiochemistry was observed for substitution at C2/C4 with selectivity > 50:1 noted. All analogues were screened for their ability to interact with CRH1 and CRH2 receptors. In all instances only poor agonistic and/or antagonistic behaviour was noted at CRH2. However
以中等到良好的产率合成了四个小的,差异取代的氨基嘧啶的靶向库。在C2 / C4处观察到出色的区域化学取代作用,选择性> 50:1。筛选所有类似物与CRH1和CRH2受体相互作用的能力。在所有情况下,在CRH2处仅观察到不良的激动和/或拮抗行为。但是,有几种化合物是有效的和选择性的CRH1拮抗剂,最值得注意的是13a Ki = 39 nM。另外,我们利用了这些数据以及其他人最近报告的数据来完善我们原始的CRH1药效团(J Med。Chem。,1999,42,2351-2357)。
